【Hormones that control your appetites】Leptin is a hormone produced by fat cells, which provides fullness, reduces fat synthesis, and helps weight control. Ghrelin is a hormone secreted by the stomach, which increases appetite and fat synthesis in the body.
Under a normal and regular lifestyle, when the body's fat increases, the level of leptin in the blood will increase, which causes the brain to suppress appetite, increase the metabolic rate, and reduce the accumulation of fat. But when we are under too much stress, severe body inflammation or excessive dieting, the level of leptin in blood will drop, leptin resistance will be induced. Leptin resistance will reduce the body's sensitivity to leptin and increase the pursuit of high-oil and high-sugar foods. Ghrelin will also increase our appetite, reduce our metabolic rate, increase fat accumulation, and create a vicious circle, which is one of the main causes of obesity.
The level of ghrelin will also be increased, which increases our appetite, reduces our metabolic rate, increases fat accumulation, and creates a vicious circle.
This shows that if you want to build a lean body, you must first improve your living habits to make your body more sensitive to leptin and reduce the level of ghrelin. We will introduce foods that can increase leptin sensitivity of our body in an upcoming post.
